This 10-13 Toyota Prius cold air intake is from Injen's premiere SP line of intakes.
Injen is probably the last true performance intake company left. If you look at an Injen intake, it immediately stands out as being thicker than other intakes. In addition, they tend to be shaped unusually. That's because they don't breeze through R&D to just bring a passable intake to market. They spend a lot of time to create the absolute perfect intake for your Prius.
The SP Cold Air line of intakes is Injen's premiere intake line. They use MR technology to create a multi-diameter intake that produces optimal power, in a cold air design that pulls colder denser air from outside the engine bay. They also pay special attention to your MAF sensor, tuning their intakes not to give too much or too little air to confuse your Prius's computer.
